Two formats, both made from the same Egyptian loofah. The Hand version (12 × 17 cm) has a cotton strap across the back and cotton trim around the edge, sized to fit one hand securely. The Sponge version (15 × 13 cm) is cut straight from a whole gourd with no cotton at all, which is why it dries the fastest. Egyptian loofah is denser and larger than the Asian variety used in most loofahs, which is why Mandisa works with it. The dark flecks inside are loofah seeds. Mandisa shakes most of them out by hand during processing, but a few always remain, and they're harmless. Each is sold as a set of two of the same format. Both ship compressed and feel stiff when dry. Soak in warm water for at least five minutes before the first use, and the loofah expands and softens as it absorbs water. After that, it firms up between uses but rehydrates the moment it gets wet. Lather body wash directly into the loofah and scrub. Rinse thoroughly, squeeze out the water, and hang to dry in a ventilated spot.
